This was in one of the feeds I read through recently..

Its talking about the kernel "notify" interface which can be told to
monitor file systems and report on changes. Something like this wrapped
in a bash script and calling unison (for example) might be what you are
after.. Unison will work with both windows and linux for file
synchronisation. There are a couple of tricks with windows. The most
notable making sure you have 

   perms=0

in your sync profile. This tells unison not to sync permissions. There
is another one that tells windows to do a "fast check" when syncing but
I don't have that on me right at this moment. 

Hope this helps
